Fall in Charleston brings a welcome change from the intense summer heat. The mornings start to cool off, windows open a little more, and air conditioning systems get a bit of a break. But just because you’re giving your AC less of a workout doesn’t mean you can completely take your eyes off it. If it’s not properly maintained during the transition, you could be in for some surprises when temperatures swing or spike again.

A lot of folks think fall is the off-season for their AC, which tends to push maintenance down the priorities list. But this short period of mild weather is actually a perfect time to make sure your system is running its best. By handling a few basics now, your home stays more comfortable and your system works more efficiently when you need it.

Inspect And Clean The AC Unit

It might seem simple, but cleaning your AC unit is one of the most useful things you can do this fall. Leaves, dirt, and pollen can build up around the outdoor unit, while indoor filters get clogged with dust. Both issues make the system work harder than it needs to, which can lead to problems with airflow or less cooling when you need it again.

Here are a few places worth giving attention:

– Air filters: Replace or clean them if they’re dirty or if it’s been a while. Dirty filters block airflow and can slow your system down.

– Coils: Both the evaporator coil inside and the condenser coil outside collect dirt over time. This reduces your system’s ability to absorb and release heat.

– Outdoor unit: Remove leaves, grass, and debris from around the base. Keep about two feet of clearance on all sides so airflow stays steady.

Even though these seem like minor tasks, they play a big part in keeping your system from wasting energy or wearing itself out too soon. If it’s been months since your AC’s been looked at, now’s a good time to schedule a thorough inspection with a technician who knows what to check and can spot anything starting to go wrong.

Check And Seal Ductwork

Leaky ducts are a hidden issue that can mess with comfort and efficiency. Air that escapes before reaching the rooms in your home leads to uneven cooling and higher energy bills. Most folks don’t even realize it’s happening until airflow starts feeling weaker in certain rooms or the system runs longer than usual.

Fall is a good time to check your ductwork because you’re not relying on the system as heavily. Look for:

– Dust buildup on vents and registers, which can signal leaks or poor airflow

– Loose or disconnected joints in accessible duct areas

– Air temperature differences between rooms, even when the system is running

Professional duct sealing helps close off those gaps and restores proper balance to your cooling system. Beyond comfort, sealed ducts also help your indoor air quality by cutting down on dust or particles getting pulled in and spread around your house. It’s one of those fixes that stays out of sight but makes a big difference day to day.

Adjust Thermostat Settings for Fall

With the shift in temperatures, taking a few minutes to adjust your thermostat settings can help trim down energy use and keep things comfortable. As things cool off in the mornings and evenings, you can lower the thermostat during times when you’re asleep or away from the house without noticing a drop in comfort.

If you’re using a programmable or smart thermostat, you’ve got even more tools to stay in control throughout the fall:

– Set schedules: Let your thermostat automatically adjust based on your routine. Comfort when you’re home, savings when you’re not.

– Remote access: Control your settings from an app, even if you’re out of town or working late.

– Energy tracking: See how your settings affect your usage and look for chances to make small tweaks for better results.

Being smart with your thermostat can take pressure off your AC, which helps it last longer and run more smoothly when you actually need it. This is also a great time to try out different settings and figure out what works best for your schedule and preferences.

Schedule a Professional Tune-Up

Tuning up your AC might not be the most exciting task this fall, but it comes with a lot of upside. A proper tune-up checks and adjusts all the key components so your system runs the way it should. Catching small issues early can save you from bigger repairs down the road.

When a technician performs a tune-up, they will usually:

– Check refrigerant levels and test for leaks

– Clean and inspect coils and fins

– Verify thermostat settings and test programming

– Examine electrical connections and safety components

Having a professional tune-up gives you peace of mind. You’ll be ready for those random fall warm-ups and make sure your system doesn’t have any hidden trouble brewing. It’s also one of the simplest ways to keep your AC prepped and reliable for the seasons ahead.

Let our team at Coastal Carolina Comfort help you take that step. Trained experts who understand the weather patterns in Charleston can look over your unit with a local eye, making sure that your system is tuned to meet your home’s needs.

A Smooth-Running System Means a Smoother Season

Getting your AC in shape for the fall doesn’t take much effort, but it does go a long way toward keeping your home comfortable. Charleston’s fall season is a great opportunity to stay ahead of potential issues by tackling key maintenance steps while the weather’s milder.

Cleaning your unit, inspecting ducts, rethinking thermostat settings, and planning professional care may seem small, but they all add up. They help your system run better, use less energy, and last longer. Your fall should be about enjoying the cooler evenings and open windows, not worrying about whether your AC will keep holding up.

Stay ahead by keeping things simple and proactive. When your AC is running right, it’s one less thing calling for your attention later. Let us help you keep things cool, steady, and comfortable all season long.

My AC Won’t Turn On: Troubleshooting Before You Call a Technician

My AC Won’t Turn On: Troubleshooting Before You Call a Technician When your AC system won’t turn on at all — no fan, no compressor, no response to thermostat changes — the cause is either an interruption in the electrical supply reaching the system (tripped breaker, blown fuse, safety switch activation, thermostat failure) or a failure of a startup component within the system itself (dead capacitor, burned contactor, failed control board, or seized compressor). About 30% of “AC won’t start” calls that Coastal Carolina Comfort responds to across South Carolina are resolved by the homeowner checks described below. The remaining 70% require professional diagnosis and repair. Coastal Carolina Comfort provides same-day diagnostic service for systems that won’t start across Summerville, Charleston, Columbia, and the entire Lowcountry and Midlands. Our NATE-certified technicians carry the common startup components — capacitors, contactors, control boards — needed to restore your system in a single visit. Call (843) 708-8735. Homeowner Troubleshooting: 6 Checks Before You Call These checks are safe for any homeowner to perform and take less than 10 minutes total. Work through them in order. Check 1: Thermostat Power and Settings Start at the thermostat — it’s the most common cause of a system that appears dead. Verify it has power. If the display is blank, the thermostat has lost power. Check whether it uses batteries (replace them) or is wired to the system (a tripped breaker or blown fuse at the air handler may have cut power to the thermostat). Verify the settings. Ensure the system is set to “cool” (not “off,” “heat,” or “fan only”), the set temperature is at least 3–5°F below the current room temperature, and any scheduling or away modes aren’t overriding your settings. Try a hard reset. Turn the thermostat completely off, wait 30 seconds, then turn it back to cooling mode. For smart thermostats, a power cycle or factory reset can resolve software glitches that prevent the system from responding. If the thermostat appears to be working correctly — display is on, settings are correct, it shows “cooling” — but the system doesn’t respond, the issue is downstream. Check 2: Circuit Breakers Your AC system typically uses two circuit breakers in your main electrical panel: one for the indoor air handler and one for the outdoor condenser unit. Check both. Look for a tripped breaker. A tripped breaker sits in the middle position — not fully “on” and not fully “off.” Push it firmly to “off” first, then back to “on.” If the breaker holds and the system starts, monitor it. If the breaker trips again within minutes, do not reset it a third time — the system has an electrical fault that requires professional diagnosis. Check for a blown fuse at the air handler. Some air handlers have a small fuse (typically 3–5 amp) on the control board that protects the low-voltage circuit. If this fuse blows, the thermostat loses its ability to communicate with the system. This fuse is accessible inside the air handler’s front panel — but if you’re not comfortable opening the panel, skip this check and call for service. Check 3: Emergency Shutoff Switch Many AC installations include a wall-mounted emergency shutoff switch that looks like a standard light switch — typically located near the indoor air handler or in the utility closet. If someone accidentally flipped this switch off (during maintenance, painting, or cleaning), the entire system is disabled. Check for a switch near the air handler that might be in the “off” position. Flip it on and see if the system responds. Check 4: Condensate Drain Safety Switch Many South Carolina HVAC installations include a float switch on the condensate drain line that shuts the system down when the drain line clogs and water backs up. This is a safety feature designed to prevent water damage — but it also means a simple drain clog can make your entire AC system unresponsive. If your system has a visible float switch on the drain line (a small device with a float attached to the PVC pipe near the air handler), check whether standing water is visible in the drain pan. If the pan is full, the float switch has activated. Clearing the drain line may restore system operation. Our guide on AC leaking water inside your house covers drain line clearing in detail. Check 5: Outdoor Disconnect Box Near your outdoor condenser unit, there’s a disconnect box — a small metal box mounted on the wall within a few feet of the unit. This box contains either a pull-out fuse block or a breaker that supplies power specifically to the outdoor unit. Check that the disconnect is in the “on” position and that the fuses (if applicable) haven’t blown. A blown disconnect fuse is a common cause of a system where the indoor fan runs but the outdoor unit doesn’t respond at all. Check 6: Wait 5 Minutes After Any Reset Modern AC systems have built-in time delays that prevent the compressor from restarting too quickly after a shutdown — rapid cycling can damage the compressor. If you’ve reset a breaker, flipped a switch, or changed the thermostat, wait at least 5 minutes before concluding the system isn’t responding. The delay is protecting your equipment. If the Homeowner Checks Don’t Work: Common Professional Repairs When all homeowner-accessible checks fail to restore the system, one of these mechanical or electrical failures is typically the cause. Failed Capacitor The run capacitor provides the electrical boost the compressor and fan motors need to start. When it fails, the motors can’t overcome their starting inertia. You might hear a clicking sound from the outdoor unit as the contactor engages, followed by a hum and then silence — the system is trying to start but the capacitor can’t deliver. Capacitor failure is the single most common reason an AC system won’t start. It’s also one of the most affordable repairs: $150–$300 including parts and labor. In South Carolina’s long cooling season, capacitors endure more

AC Frozen Evaporator Coil: Why Your Air Conditioner Ices Up in Humid SC Weather

AC Frozen Evaporator Coil: Why Your Air Conditioner Ices Up in Humid SC Weather A frozen evaporator coil occurs when the coil’s surface temperature drops below 32°F and moisture from your indoor air freezes on contact, building a layer of ice that blocks airflow and prevents heat absorption. The most common causes are restricted airflow from a clogged filter or dirty coil, low refrigerant charge from a leak, and blower motor failure that reduces air volume across the coil. In South Carolina’s high-humidity environment, frozen coils are both more common and more damaging than in drier climates — the heavy moisture content in Lowcountry and Midlands air means ice builds faster and produces more water when it melts. Coastal Carolina Comfort diagnoses and repairs frozen evaporator coils across Summerville, Charleston, Columbia, and all of South Carolina. Our NATE-certified technicians identify the root cause — not just thaw the ice — and provide upfront pricing before any repair begins. Call (843) 708-8735. How a Frozen Coil Damages Your AC System A frozen evaporator coil isn’t just a temporary inconvenience — it creates a cascade of problems that can damage multiple components if the system continues running. The compressor is at greatest risk. Under normal operation, liquid refrigerant enters the evaporator coil, absorbs heat, and exits as a gas before returning to the compressor. When the coil freezes, this heat exchange stops. Liquid refrigerant passes through the coil without vaporizing and reaches the compressor in liquid form. Compressors are designed to pump gas, not liquid. Liquid refrigerant entering the compressor — called liquid slugging — can crack valves, damage pistons, and cause catastrophic compressor failure. A compressor replacement typically costs $1,500–$3,000+. Water damage when the ice melts. A frozen coil accumulates a surprising amount of ice. When the system shuts off or the ice begins to melt, the resulting water can easily overwhelm the drain pan — especially if the drain line is also partially clogged (a common combination in South Carolina). Water overflows onto floors, into ceilings, or through walls. Read our guide on AC leaking water inside your house for immediate steps if you’re already dealing with water. Reduced system life. Repeated freeze-thaw cycles stress the coil fins, degrade the coil’s protective coating, and can eventually cause refrigerant leaks in the coil itself — one of the most expensive AC repairs. The 5 Causes of Frozen Evaporator Coils in South Carolina 1. Clogged Air Filter This is the most common cause — and the most preventable. A clogged filter restricts the volume of warm air passing over the evaporator coil. Without sufficient warm air, the coil’s temperature drops below the freezing point. Moisture in the air freezes on contact, and the ice layer further restricts airflow, accelerating the freeze. In South Carolina, where pet dander, pollen, dust, and high humidity all contribute to faster filter loading, a filter that might last 90 days in a drier climate may need replacement every 30 days during peak cooling season. The fix: Replace the filter, turn the system off for 2–3 hours to allow complete thawing, then restart. If the system runs normally and doesn’t refreeze, the filter was the sole cause. If ice returns within 24 hours, there’s an additional underlying issue. 2. Low Refrigerant From a Leak Low refrigerant charge causes the evaporator coil’s temperature to drop below normal operating range. When the coil is too cold, moisture freezes on its surface instead of condensing into liquid and draining away. The ice insulates the coil, making it even colder, and the freeze accelerates until the coil is completely encased. This is the most common mechanical cause of frozen coils, and it requires professional repair. A technician will thaw the coil, test for leaks, repair the leak source, and recharge the system to manufacturer specifications. Simply adding refrigerant without fixing the leak guarantees the problem will return. In South Carolina’s coastal environment, refrigerant line corrosion from salt air is a significant contributor to leaks — particularly on homes within a few miles of Charleston Harbor, James Island, or the Isle of Palms. 3. Dirty Evaporator Coil Even with regular filter changes, the evaporator coil accumulates dust, biological growth, and particulate matter over time — especially in South Carolina’s humid environment where mold and mildew thrive on the constantly damp coil surface. A dirty coil insulates itself from the warm air passing over it. The coil can’t absorb enough heat, its temperature drops, and the same freeze cycle begins. The difference is that a dirty-coil freeze develops more gradually than a low-refrigerant freeze — you might notice declining performance for weeks before ice becomes visible. The fix: Professional coil cleaning. This requires access to the indoor unit, coil-specific cleaning solution, and careful handling to avoid damaging the delicate aluminum fins. Coil cleaning is typically included in comprehensive maintenance visits that prevent frozen coils and costs $150–$300 as a standalone service. 4. Blower Motor Failure or Reduction The blower motor moves air across the evaporator coil. If it fails entirely, airflow stops completely and the coil freezes rapidly. A partially failing motor — running at reduced speed due to worn bearings, a failing capacitor, or a winding issue — moves insufficient air, causing a slower but equally damaging freeze. In multi-speed systems, a motor stuck on low speed may provide enough airflow for mild days but insufficient volume on high-demand days, creating intermittent freezing that’s harder to diagnose. 5. Collapsed or Blocked Return Ductwork If the return duct — the large duct that carries warm room air back to the air handler — is crushed, disconnected, or severely blocked, the volume of air reaching the evaporator coil drops below the minimum threshold. This can happen when stored items are placed on flex duct in an attic, when a duct joint separates due to age or poor installation, or when a return vent is blocked by furniture or closed. This cause is more common in homes with ductwork routed through attics — a standard
